Riboflavin Deficiency in Fowls

Abstract

DEFICIENCY of riboflavin (vitamin B₂) in chick rations leads to poor growth and may give rise to, 'curled toe paralysis'. Where skim milk is available, this trouble is unlikely to occur; but under war-time conditions rearers are forced to depend chiefly on mashes. Official regulations have ensured that all rearing mixtures contain adequate riboflavin; but owing to the fact that essential ingredients such as dried skim milk and dried yeast are in short supply, the possibility of using an alternative source of the vitamin has been investigated by the Chemical Division of the Agricultural Research Institute of Northern Ireland.
